What is H202 QuickBooks Error?

The error message may read:

“This company file is on another computer, and QuickBooks needs some help connecting.”

This indicates a communication error due to firewall issues, DNS settings, incorrect hosting configuration, or problems with QuickBooks Database Server Manager.

Step-by-Step Guide to Fix QuickBooks Error H202

1. Use QuickBooks Database Server Manager

The first thing to try is to scan the folder containing your company file using QuickBooks Database Server Manager.

Go to the server computer (where the company file is stored).
Open the QuickBooks Tool Hub (if you don’t have it, you can download and install it).
Navigate to Network Issues and open QuickBooks Database Server Manager.
Click Browse, select your company file folder, and click Start Scan.
Once the scan completes, open QuickBooks on the workstation and try again.

2. Check QuickBooks Hosting Settings

To avoid QuickBooks host multi-user access error, verify that only the server system is hosting the company file.

On all workstations, open QuickBooks and go to File > Utilities.
If you see “Host Multi-User Access”, do nothing.
If you see “Stop Hosting Multi-User Access”, select it to disable hosting.
Only the server should have hosting enabled.

3. Verify QuickBooks Services Are Running

Check that essential QuickBooks services are running on the server.

Press Windows + R, type services.msc, and press Enter.
Look for QuickBooksDBXX (XX depends on the version) and QBCFMonitorService.
Ensure both are running and set to Automatic.

If they aren’t running, right-click each and choose Start.

4. Configure Windows Firewall Settings

QuickBooks firewall settings error can cause QuickBooks to block incoming/outgoing connections, leading to the H202 error.

Open Windows Defender Firewall.
Go to Advanced Settings > Inbound Rules > New Rule.
Add exceptions for the following ports based on your version:
- QuickBooks 2022: 8019, 56728, 55378-55382
- QuickBooks 2021: 8019, 56727, 55373-55377
